Question

Add -3a+ 2b + c and 3a+2 b- c
​

Answer 1

Answer:

= -3a+2b+c + 3a+2b-c

= 4b

Answer 2

• We have to evaluate the above expression by using the given data.

            Given data:- $(-3a+2b+c)+(3a+2b-c).$

            To find:-Value of the given expression.

            Solution:-  

• Adding two or more numbers together is known as an addition.

• Addition as denoted by(+).

• Properties of addition are as follows,

1. Identity property of zero.
2. Inverse property.
3. Commutative property.
4. Associative property.

         Therefore,

        $(-3a+2b+c)+(3a+2b-c)\\=>-3 a+2 b+c+3 a+2 b-c\\=>-3 a+3 a+2 b+2 b+c-c\\=>2 b+2 b+c-c\\=>4 b+c-c\\=>4b.$

 Hence we will get the value $(-3a+2b+c)+(3a+2b-c)=4b.$
